  1. 1. Metabolic effects of interleukin-6

    Författare :Ingrid Wernstedt; Göteborgs universitet; []
    Nyckelord :IL-6; cytokine; obesity; energy expenditure; lipolysis; ASP; sympathetic nervous system; exercise; -174 G C IL-6 polymorphism; fat mass; stress response; cerebrospinal fluid;

    Sammanfattning : The levels of the cytokine interleukin-6 (IL-6) in the circulation are positively correlated with indices of obesity and metabolic disturbances. Paradoxically, plasma IL-6 levels increase markedly during prolonged and strenuous exercise, mainly due to increased production and release from working skeletal muscle. LÄS MER

    Sammanfattning : Obesity and related complications such as diabetes mellitus type 2 (T2DM) and cardiovascular events, are a growing major health problem worldwide. Achieving a negative energy balance by increasing physical activity in combination with reduced caloric intake, is the most common approach in weight reduction strategies, something that is difficult to maintain in the long term.

  4. 3. Endogenous antioxidants in human skeletal muscle and adaption in energy metabolism : with reference to exercise-training, exercise-related factors and nutrition

    Författare :Michael B Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :GSH; urate; Q10; Ubiquinone-10; myoblasts; muscle stem cells; high-intensity exercise; performance; overload training; adenine nucleotides; AMP deaminase; glycogen; carbohydrates.;

    Sammanfattning : The antioxidant homeostasis is determined by a wide array of interacting cellular antioxidants, as well as being influenced by the homeostasis in energy metabolism. Changes in antioxidant homeostasis, as a consequences of altered production of reactive oxygen species (ROS). and/or by changes in the resident levels of antioxidants. LÄS MER

  5. 4. Immunological changes in human blood and skeletal muscle in response to physical exercise

    Författare :Christer Malm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Eccentric exercise; soccer; football; adaptation; immune system; muscle; inflammation; damage; leukocytes; growth factors; cytokines; adhesion; signaling; hormones.;

    Sammanfattning : Physical exercise is essential for maintaining normal function of skeletal muscle. Muscle tissue also has a remarkable capacity for adaptation to changes in physical demand. In fact, without stimulation from physical activity, muscle tissue will atrophy. LÄS MER

  7. 5. Menstrual status and long-term cardiovascular effects of intense exercise in top elite athlete women

    Författare :Magnus Hagmar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Elite athletes; female athlete triad; BMI; energy deficiency; amenorrhea; polycystic ovary syndrome; body composition; bone mineral density; postmenopausal women; endothelial function; athlete s heart; echocardiography; exercise test.;

    Sammanfattning : Although physical exercise is generally beneficial for health, female athletes run an elevated risk of developing chronic energy deficiency, with ensuing severe consequences such as reproductive dysfunction, bone demineralization, more frequent injuries, impaired performance, and adverse cardiovascular effects. However, at present little is known about these issues with respect to sportswomen competing at the Olympic level, or about the long-term cardiovascular consequences of intense training for women.
